Alright I'm impressed with this. #wallabag can generate RSS feeds of your unread articles. I didn't think about this before now but that means I can throw wallabag a link using the browser extension while I'm working on something and it will be downloaded to wallabag then to #TinyTinyRSS and from there, it's downloaded to my phone. With hardly any effort (aside from setting them up), I can read any article offline in a single app.
